Package description
The `which-typed-array` npm package is designed to identify the type of a given typed array instance. It supports all built-in JavaScript typed array types, including `Int8Array`, `Uint8Array`, `Uint8ClampedArray`, `Int16Array`, `Uint16Array`, `Int32Array`, `Uint32Array`, `Float32Array`, `Float64Array`, and `BigInt64Array`, `BigUint64Array`. This package is useful for applications that need to process or manipulate typed arrays and must determine their specific types to apply the correct operations.
Identifying Typed Array Type
This feature allows the identification of the type of a typed array. The function `whichTypedArray` is called with a typed array as its argument, and it returns a string representing the type of the typed array.
"use strict";\nconst whichTypedArray = require('which-typed-array');\nconsole.log(whichTypedArray(new Uint8Array())); // 'Uint8Array'\nconsole.log(whichTypedArray(new Float32Array())); // 'Float32Array'"The `is-typedarray` package is similar to `which-typed-array` in that it is used to check if a given object is a typed array. However, unlike `which-typed-array`, it does not specify the type of the typed array; it only checks if the object is a typed array or not.
The `typedarray-detection` package offers functionality similar to `which-typed-array` by allowing the detection of typed array types. It provides a more extensive set of utilities for working with typed arrays, including functions to check for specific types of typed arrays, but it might not be as straightforward or focused as `which-typed-array` for simply identifying the typed array type.
